Good work on providing a utility!... although it seems that this utility ( looking at the C code) is meant for getting data using the Serial (over USB) port on the Watts Up meters... is that correct?

Does anyone know if there exists a similar utility to get data off a .Net meter using TCP/IP directly ? I basically want to be able to query my .Net meter directly without going through the watts-up meter website ...

I checked /dev directory and found /dev/ttyUSB0. It shows this meter has been connected. I am wondering whether I need the driver for this device but I couldn’t find one for Linux through the Watts Up website.

thanks to the author for this wonderful tool.. i have a few questions regarding the data shown by this tool.. Is the output that we get the live output? I ask this question because the windows version of this similar tool samples at 1 second and when the memory in wattsup-pro is exhausted, it increases the sampling rate by 2. Hence as time progresses, the output becomes less accurate.. Does this tool work the same way or does it show the live output..Also, is it possible to reduce the sampling rate from 1 sec to less than a sec.. i tried changing the wu_interval in the code to sleep for 100 millisecond but i got a segfault.. any help will be really appreciated.

the arguments are always ttyUSB0 or something like that and not /dev/ttyUSB0 (/dev is removed). Also search whether the device comes up as a tty device, i dont think you can read from it as a u* device

I am a new user of Watts up. Now, I want to test power consumption of my program under centos 5.4. Thank you for sharing your watts up linux utility. What I am trying to do is I want to clear the memory of the watts up meter and start to logging in the power consumption before my program starts, and finally collect all the data when my program finishs. However, if I add the ./wattsup ttyUSB0 command into my program, it will keep running this command which stops the execution of the rest of my program. I do not know how to solve this problem? Could you give me some suggestions? Thank you for your helps.

I am using this linux utility on Ubuntu 12.10. One problem i am facing is when i use the utility for some time, it start giving error for timer expiry for data read. I remove the USB cable and connect it again. I then get a new ttyUSB and the utility start again and it works fine.

Many thanks to the original author of this tool, Patrick Mochel; and to Peter Bailey for providing a fork of this code on github.

Before stumbling across this forum, I had also tinkered with the code to make it usable with pipes, and in fact I came to this forum to see who I should contact about forking the code on github. So I'm really glad that Peter has done this already! But it would have been nice to have known about Peter's version before I spent time tinkering with the code.

So...

Dear WattsUp folks, please could you consider changing your "Support: Downloads" web page so it links to Peter Bailey's github version of this code rather than the old .zip file?
